BURNER.

Specification of Letters Patent.

Patented Nov. 10, 1908.

Application filed January 18, 1908. Serial No. 411,473.

To all whom it may concern:

Be it known that I, FRANCIS J. ALBRECHT, a citizen of the United Statesof America, residing at Pittsburg, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inBurners, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to gas burners particularly designed for ovens.

My invention aims to provide a novel burner having an air mixer toinsure perfect combustion, whereby a high degree of heat can be obtainedfrom a minimum amount of gas.

My burner is particularly adapted for bakers ovens, and is constructedwhereby it can be easily placed in an oven and adjusted according to themanner in which the oven is to be heated.

To this end, I have devised a simple and inexpensive gas burner that canbe used in an oven designed to be heated by fuel other than gas,therefore my gas burner is applicable to various types of bakers ovens,and the many other advantages of my invention will be apparent to bakersand such artisans having use for the burner.-

The invention will be now described in detail, and reference will firstbe had to the accompanying drawing forming a part of this specification,wherein,

Figure 1 is a side elevation of my burner, as mounted in an oven, F ig.2 is a horizontal sectional view of the burner, and Fig. 3 is alongitudinal sectional view of the same.

To put my invention into practice, I construct my burner of a casingcomprising a tee 1 having a plurality of nipples 2. The tee 1 isprovided with a pipe 3 adapted to be connected by a hose 4 generally aflexible hose to a gas supply pipe 5, this gas supply pipe having asuitable valve (not shown) for controlling the admission of gas to theburner. The tee 1 is formed with a central outwardly extending lug 6 andsecured to said lug by a bolt 7 and a nut 8 is a metallic casing 9,preferably made of sheet metal. This casing is adapted to surround allof the nipples 2, and has its outer end flared. In the casing isarranged a plurality of metallic pipes 10, said pipes having their innerends in close proximity to the nipples 2, while their outer ends areapproximately flush with the outer flared end of the casing 9. Thesepipes are secured in the casing by screws 11.

The top and bottom of the casing 9 adjacent to the nipples 2 areprovided with triangular shaped openings 12, the material from theseopenings being bent upwardly, as at 13 to engage the tee 1. The top andbottom of the casing, adjacent to the flared end, are provided withtriangular shaped openings 14 and the material from these openings isbent into the casing, as at 15. An additional bolt 16 and nuts 17 areemployed for further holding the casing 9 upon the pipes 10.

Upon the top of the casing I arrange a longitudinal strengthening strip18, this strip being held by the bolts 7 and 16, also by a screw 19fixed in the tee 1.

In practice, the flared end of the casing 9 is adapted to rest upon thebridge wall 20 of an oven, while the rear end thereof rests upon thegrate bars 21 of the oven, and the pipe 3 extends downwardly through thegrate bars and under the oven door 22.

It is a well known fact that the escape of gas from the pipe 5 into theoven often causes an explosion, therefore I use a flexi-' ble hose 4:,adapted to be detached when the burner is not being used, thiis allowinggas to escape outside of the oven, should there be a leak in thecontrolling valve of the pipe 5.

Air entering the openings 12 and 1a is adapted to commingle with the gasprojected into the pipes 10 from the nipples 2, and with the gas that isprojected from the outer end of the pipes 10.

The burner can be used with either side up, and can be shifted in theoven to proj eat a flame against either side thereof. To remove theburner from the oven, it is only necessary to detach the hose 4, pushthe burner inwardly until the pipe 3 passes up through the grate bars21, and then remove the same bodily through the door-way of the ovendoor 22.

I reserve the right to make my burner any size and of any material.

Having now described my invention what I claim as new, is

1. A burner comprising a tee, nipples carried by said tee, an outwardlyextending lug carried by said tee, a metallic asing surrounding saidnipples and having a flared end and connecting with said lug, aplurality of pipes arranged within said casing and extending in closeproximity to said nipples, said casing having openings formed thereinfor admitting air, some of said openings being close to said nipples andthe inner ends of said pipes, and means for securing said pipes withinsaid casin 2. A burner comprising a tee, nipples carried thereby, a lugprojecting from said tee, a casing surrounding said nipples and attachedto said lug, a plurality of outwardly inclined pipes arranged inparallelism with respect to each other and positioned within saidcasing, said pipes having their inner ends in close proximity to butspaced from said nipples, said casing having openin s formed thereinnear its outer end and at its inner end in close proximity to thenipples, means for securing said pipes in said casing, and means forsecuring said casing to said tee.

In testimony whereof I aflix my signature in the presence of twowitnesses.
